Postdoc Maximilian Günther is the lead author on a paper showing that NASA’s TESS satellite has discovered three new exoplanets. “The exoplanets are of a type that does not exist in our solar system, being between the Earth and Neptune in size,” writes Daniel Clery for Science. “That makes the closely packed system, known as TOI-270, a good bet for answering long-standing questions about how such ‘super-Earths’ or ‘mini-Neptunes’ form.”
TESS, an MIT-led NASA mission, has discovered two gaseous exoplanets and one rocky exoplanet within a system known as TOI-270, reports New Scientist. “TOI-270 will soon allow us to study this ‘missing link’ between rocky Earth-like planets and gas-dominant mini-Neptunes, because here all of these types formed in the same system,” says postdoc Maximilian Günther, lead author of a paper on the new system.
Blue Origin unveiled plans to send a spaceship to the moon, reports Seth Borenstein for the AP. Prof. Dava Newman explained that the newly designed rocket engine is what makes Blue Origin’s attempt to reach the moon unique. “It’s for real,” said Newman.
A new study by MIT researchers provides evidence that life on Earth may have begun in shallow bodies of water, reports Martin Finucane for The Boston Globe. The researchers found that ponds “could have held high concentrations of a key ingredient, nitrogen, while that would have been less likely in the ocean,” Finucane explains.
Boston Globe reporter Martin Finucane writes about how TESS has discovered an Earth-sized planet orbiting a star 52 light years from Earth. “The new planet HD, 21749c, orbits the star HD 21749. It circles the star in 7.8 days,” Finucane explains. “The planet is probably rocky and uninhabitable, with temperatures on the surface of up to 800 degrees.”
Forbes contributor Jamie Carter writes that TESS has identified an Earth-sized exoplanet orbiting a star 52 light years from Earth. The planet "takes about eight days to orbit the host star and is similar in size to Earth at 89% its diameter,” writes Carter. “A likely rocky world, it's thought to have surface temperatures as high as 800°F /427°C.”
The MIT-led TESS mission has discovered its first Earth-sized exoplanet, reports Ashley Strickland for CNN. “There was quite some detective work involved, and the right people were there at the right time,” says postdoctoral fellow Diana Dragomir. “But we were lucky, and we caught the signals, and they were really clear."
A new study by MIT researchers provides evidence that the first life on Earth likely came from shallow ponds, not oceans, reports the Xinhua news agency. The researchers found that primitive ponds that were about “10 centimeters deep had higher concentrations of nitrogen, a key ingredient for life on Earth.”
LiveScience reporter Stephanie Pappas writes that a new study by MIT researchers finds that massive tectonic collisions in the tropics may have led to the last three ice ages on Earth. “This could provide a simple tectonic process that explains how Earth goes in and out of glacial periods,” explains Prof. Oliver Jagoutz.
Nature reporter Alexandra Witze highlights the TESS satellite’s success in uncovering new exoplanets outside our solar system. Senior research scientist George Ricker feels, “TESS works better than team members had dared to dream,” Witze writes, adding that “its four cameras can see objects 20% fainter, and focus more sharply, than originally expected.”
NASA’s MIT-led TESS mission has discovered a new exoplanet orbiting a star 53 light years from Earth, reports Mike Wall for Space.com. The “sub-Neptune” planet is “about three times bigger than Earth, which means it's likely gaseous rather than rocky,” writes Wall.
CNN reporter Ashley Strickland writes that NASA’s planet-hunting satellite TESS has discovered another exoplanet 53 light years away. Strickland explains that the exoplanet orbits “a bright neighboring star in the Reticulum constellation, with a 36-day orbit and a surface temperature of 300 degrees Fahrenheit.”
NASA’s MIT-led TESS mission has discovered a new exoplanet that is about three times the size of Earth, reports Dennis Overbye for The New York Times. “There was quite some detective work involved, and the right people were there at the right time,” explains postdoctoral fellow Diana Dragomir. “But we were lucky, and we caught the signals, and they were really clear.”
Verge reporter Loren Grush writes that NASA’s MIT-led TESS mission has discovered a third exoplanet. “The important thing about this system that’s especially unique is it’s near to us,” says postdoc Diana Dragomir. “What that means simply is we can study this system in detail. We can measure the mass of the planet and measure things about the star.”
TechCrunch reporter Devin Coldewey highlights how MIT researchers have found that tiny satellites, called CubeSats, equipped with lasers could help keep telescopes on track while they are gathering information in space. The light emitted from the lasers could allow satellites “to calculate their position and the minute changes to their imaging apparatus caused by heat and radiation.”
